introduction of Shared memoryshared memory is one of three IPC (inter-process communication) mechanisms. It allows two unrelated processes to access the same logical memory. shared memory is a very efficient way to pass data between two processes

The Unified Call uses MMAP () to map a common file to implement shared memory. System V maps files in the SHM of a special file system to implement shared memory communication between processes. That is to say, each shared memory area corresponds to
